Busway Enclosure Venting for Condensate Drainage and Moisture Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Outdoor busway systems face issues with condensation accumulation and moisture ingress, which can be detrimental to electrical performance, and existing solutions fail to maintain internal pressure equal to ambient atmospheric pressure effectively.
Innovation Solution
An atmospheric vent system with a moveable spherical weight that alternately seals and drains condensate, using elastomeric bodies and gravity to manage moisture ingress and maintain internal pressure balance within the busway enclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sealing means are used to prevent moisture ingress, then moisture protection is improved, but condensate drainage capability deteriorates
Solution Approach 1:
The atmospheric vent system employs a moveable spherical weight that dynamically transitions between sealing and draining positions based on internal pressure differentials. When internal pressure exceeds ambient pressure, the weight moves to allow condensate drainage; when pressures equalize, the weight returns to seal the opening, preventing moisture ingress. This dynamic mechanism resolves the contradiction by making the sealing capability conditional rather than static.
Solution Approach 2:
The spherical weight is actuated automatically by the pressure differential between the enclosure interior and exterior without external control. The system self-regulates by using the accumulated pressure itself as the actuating force to open the vent, then automatically reseals when pressure equalizes, providing both sealing and drainage functions through self-service operation.

Solution Approach 1:
The atmospheric vent system employs a moveable spherical weight that dynamically transitions between sealing and draining positions based on internal pressure differentials. When internal pressure exceeds ambient pressure, the weight moves to allow condensate drainage; when pressures equalize, the weight returns to seal the opening, preventing moisture ingress.

Function Achieved in This Case
Effectively drains condensate while preventing moisture ingress, ensuring internal pressure equality with ambient pressure, thus enhancing the reliability and performance of outdoor busway systems.
Implementation Method 1
Alignment in vertically upright or inverted orientations cause the atmospheric vent system to seal or drain as gravity acts to move the moveable spherical weight within the body
Implementation Method 2
Each atmospheric vent of the connector housing having an elastomeric body and a spherical weight that is moveably restrained such that an internal wall engages the spherical weight to create a seal
